9557448ae6 Introduce {v,}asprintf for windows 
We have now again two functions called h_platform_vasprintf and
h_platform_asprintf. On windows they are implemented in terms of vsnprint
and the like. On BSD/GNU libraries we use the supplied vasprintf and
asprintf.

124b4c381b regex_debug.c: Stop including dlfcn.h 
Since the block of code has been disabled anyway and is not very
portable, we introduce a define to control both the include
and the code.

0c35525e30 Convert usages of errx to h_platform_errx 
This BSD call will have to be implemented on windows. Right now
we have a stub that just exits the process.

af73181cf4 Fix #118 
NEWS:
* Switching endianness mid-byte no longer potentially re-reads bytes.
* bit_offset now consistently refers to the number of bits already
  read.
* HParsedTokens now have a bit_length field; this is a size_t.  This
  may be removed for memory reasons.

The bit writer has not yet been updated to match; the result of
switching bit writer endianness in the middle of a byte remains
undefined.

c8fc061ea6 Ditch longs and long longs in favor of stdint.h types, which has cascading 
effects throughout, including use of inttypes.h/PRI[ud]64 because printf() is
still stuck in a long world, conversion of %lu to %zu for printing values of
type size_t, and changing/renaming the g_check_cmp* family of functions.
